Fracking explained in five minutes.
Fracking is a controversial topic. On the one side the gas drilling companies, on the other citizen opposed to this drilling method. Politicians are also divided on the matter.
We try to take a neutral look on fracking. It is relevant for all of us, because of high prices for energy and the danger for our drinking water.
This video focuses mostly on the debate currently ongoing in europe. In a lot of european countries there is a public outcry against fracking, espacially in germany. But the facts in this video are relevant to all of us.
Short videos, explaining things. For example Evolution, the Universe, Stock Market or controversial topics like Fracking. Because we love science.
We would love to interact more with you, our viewers to figure out what topics you want to see. If you have a suggestion for future videos or feedback, drop us a line! :)

The Amazon rainforest is one of the world's most unique and important ecosystems. Yet the health of the rainforest and the people who live there is threatened by the construction of large projects, such as energy plants, dams, highways and mines. Mott Foundation grantees are among those working to ensure that investors in these projects adopt responsible development policies and practices, and are held accountable for any negative social and environmental impacts of the projects they fund. Grantees highlighted in this video are:
• Institute for Socioeconomic Studies (INESC) -- www.inesc.org.br
• International Rivers -- www.internationalrivers.org
• Law, Environment and Natural Resources (DAR) -- www.dar.org.pe

What is CROSS-CUTTING? What does CROSS-CUTTING mean? CROSS-CUTTING meaning - CROSS-CUTTING definition - CROSS-CUTTING explanation.

Cross-cutting is an editing technique most often used in films to establish action occurring at the same time, and usually in the same place. In a cross-cut, the camera will cut away from one action to another action, which can suggest the simultaneity of these two actions but this is not always the case.
Suspense may be added by cross-cutting. It is built through the expectations that it creates and in the hopes that it will be explained with time. Cross-cutting also forms parallels; it illustrates a narrative action that happens in several places at approximately the same time. For instance, in D.W. Griffith's A Corner in Wheat (1909), the film cross-cuts between the activities of rich businessmen and poor people waiting in line for bread. This creates a sharp dichotomy between the two actions, and encourages the viewer to compare the two shots. Often, this contrast is used for strong emotional effect, and frequently at the climax of a film. The rhythm of, or length of time between, cross-cuts can also set the rhythm of a scene. Increasing the rapidity between two different actions may add tension to a scene, much in the same manner of using short, declarative sentences in a work of literature.
Cross-cutting was established as a film-making technique relatively early in film history (a few examples being Edwin Porter's 1903 short The Great Train Robbery and Louis J. Gasnier's 1908 short The Runaway Horse); Griffith was its most famous practitioner. The technique is showcased in his Biograph work, such as A Corner in Wheat and 1911's The Lonedale Operator. His 1915 film, The Birth of a Nation, contains textbook examples of cross-cutting and firmly established it as a staple of film editing. Mrinal Sen has used cross-cutting effectively in his agit-prop film Interview which achieved significant commercial success. Christopher Nolan uses cross-cutting extensively in blockbuster films such as Interstellar, The Dark Knight and Inception - particularly in the latter, in which sequences depict multiple simultaneous levels of consciousness. Cloud Atlas is known for its numerous cross-cuts between the film's six different stories, some lasting only a few seconds and others spanning across 300+ years in different locations around the world. All stories, however, are held together by similar action between the narratives in each cut.
Cross-cutting is often used during phone-conversation sequence so viewers see both characters' facial expressions in response to what is said.
